Abstract (en)
Preparation of a non-inflammable or flame-resistant laminar paper or cardboard material comprises forming a paper course based on paper pulp, forming a supersaturated borax solution, where for supersaturating an ammonium phosphate is used with borax and applying the supersaturated borax solution on the paper. An independent claim is also included for a non-inflammable or flame resistant laminar paper or cardboard comprising laminar paper layers, which are formed by the paper course, which is treated with the supersaturated borax solution.
